Congressional Democrats this week have kicked into a new gear their efforts to counter the conservative-controlled Supreme Court, a bid that’s likely to remain a frustrating one in an election year.

Following a series of decisions that gave former President Donald Trump broad immunity from federal charges, threw out a gun control rule and granted the courts more power over federal agencies, Democrats are raising the stakes to rein in the court with actions that have little chance of success given Republicans’ praise for many of the rulings.

Democrats, after years of frustrations with a court controlled 6-3 by Republican appointees and unable to muster bipartisan support for legislation, are pulling some of the few remaining levers they have: offering impeachment articles against Justices Samuel A. Alito Jr. and Clarence Thomas, deploying a House procedure to try to force a vote that could require some Republicans to buck House leadership, and promises to “work” on further Supreme Court legislation that has yet to attract GOP support.
